Abstract We have observed the core-dominated quasar 0106+013 with a global VLBI Array at γ = 6 cm in 1986 and 1988. The radio structure changed dramatically between the two epochs from barely resolved to well-separated double with flux ratio 3:2. Identifying the changes with east-west movement between two components, we find the proper motion μ = 0.20 +/- 0.5 mas yr^-1^ which corresponds to v/c = (8.2 +/- 2.0)/h (for z = 2.107; H_0_ = 100 km s^-1^ Mpc^-1^ and q_0_ = 0.5). The speed is typical of superluminal quasars. We note that 0106+013 is a key object in VLBI-based geodetic measurements; knowledge of its structure should improve the accuracy of measurements of crustal dynamics.
